Magnesia brick is a kind of alkalescency refractory brick that made from the sintered magnesium with its content of 87% and that are combined with silicate. Since its combination composition is mainly cms-m2s system, its load softening temperature is low and thermal shock resistance is poor that determine its application is few. But magnesia brick is widely sued in the furnaces and kilns that have alkaline atmosphere. The essential properties of magnesia brick depends on the nature of the raw materials, the mineral composition, microstructure and closely on the density of the products.

Refractory castable: it is our bestseller. We can supply many kinds of refractory castable, such as low cement castable, self flowing castable, high alumina castable, mullite castable, azs castable, fireclay castable, light weight refractory castable, corundum castable refractory etc.
The refractory castable is unshaped refractory material that doesn't need firing and features fluidness after adding water. Mixed by grain, fines, and binder in fixed proportion, refractory castable can replace special shaped refractory material. Refractory castable can be used directly without firing, easy to construct, and has a high utilization rate and high cold crushing strength.
The refractory castable is primarily used fro furnaces and kilns in metallurgy, petroleum, chemical industry, construction, electric power and building etc.

1.Low thermal conductivity,
2.Good thermal insulation performance.
3.Good integrity with furnace lining
Tyical features:
High compressive strength in normal temperature, high ability for anti-abrasion during work, low shrinkage degree under high temperature so as to maintaining an integrity of the furnace lining; low apparent porosity, and fe2o3 content to reduce the carbon deposit in the blowhole and avoid the bricks broken in case of expansion; seldom melting point settings shape.
Fireclay bricks are divided into different kinds which are mainly as below:
(1) normal purpose fireclay bricks
(2) fireclay bricks for coke oven
(3) fireclay bricks for blast furnace
(4) fireclay bricks for hot-blast stove
(5) glass furnace bottom fireclay blocks
(6) lower porosity fireclay bricks.

Self flowing castable.
Self flowing to narrow place.
Easy for installation.
Al2o3:40%~80%.
Iso9001:2000 certificate.
Self flowing---great advantage in installation.
These self-flowing or pumpable castables may be transported to high elevations.
This self-flowing property of a castable is indeed an installation advantage and many manufacturers are adopting their castable product line to be self-flowing.
